Just like\[\huge\color{blue}{ a \frac{b}{c} =\frac{a \times c + b}{c} }\]so to
\[\huge\color{blue}{ 2 \frac{1}{2} =\frac{2 \times 2 + 1}{2} }\]
OpenStudy (solomonzelman):
So we know that\[\huge\color{blue}{ 2 \frac{1}{2} = }\huge\color{blue}{ \frac{5}{2} }\]
OpenStudy (solomonzelman):
No lets divide, the problem is now saying,
\[\huge\color{red}{ \frac{5}{2} \div }\huge\color{red}{ \frac{1}{4} }\]
OpenStudy (anonymous):
SO is it 5/8?
OpenStudy (anonymous):

when you divide you flip the sign and multiply.
\[\huge\color{red}{ \frac{5}{2} }\times \huge\color{red}{ \frac{4}{1} }\]
OpenStudy (solomonzelman):
I should have said.
when you divide by a fraction, you flip the fraction you are dividing be, and multiply instead.
see what I did?
OpenStudy (anonymous):
oh ok so is the answer 20/2 but that does not sound right
OpenStudy (solomonzelman):
Yes, because you can reduce\[\huge\color{red}{ \frac{20}{2} }\]
OpenStudy (anonymous):
so is the answer 10? thats what i got
